Embedded Flight Software Engineer Senior

York is seeking a Senior Embedded Flight Software Engineer to design, develop, test, and deliver mission-critical software for spacecraft systems. This role focuses on real-time and embedded Linux-based flight software, enabling reliable command, telemetry, networking, and autonomy across on-orbit vehicles.

The ideal candidate is a hands-on engineer with strong systems thinking who can operate across the full lifecycle—from architecture and development through integration, test, and on-orbit support.

Not all skills below are required, we encourage you to apply if you have an interest in learning!
